Re: INTRODUCING PV BODY GUARD!!!
The obvious question: How much?
Looks awesome! I would love to add that to my collection of safety gear. I may be old school, but I just throw a pad (foam block, football dummy, wedge, etc) in the box after the kid takes off.
I can see how this would make jumping alone a lot safer for sure! Let us know the price, and maybe I can get the AD to throw in on this new-fangled technology. Good luck with it!

Any chance this device will be legal for in competition use?

Re: INTRODUCING PV BODY GUARD!!!
I honestly do not think the activator will cause that big of an issue, but just making sure that little cord across the front does not make it illegal because it is before the "Zero" mark.
Secondly. You stated that it causes 1/3 of a flex number or .00041. What are the units on that .00041? Pounds? Centimeters? 1/3 of a flex is .333cm which is about 3.333 pounds on most poles.
It obviously does not make the pole any "stiffer" because it is touching the pole so low to the ground. So my question is how did you come up with that 1/3 of a flex or .00041. Is this just how much force it takes to activate the flaps to close?
Also I think something better than comparing the resistance caused to a flex or a number in pounds. I would compare it to how much it slows down the rotation of the pole towards the box. If anyone had access to a very high speed camera they could Have someone of a certain weight hold onto a pole while standing on a platform or something and just ride it into the pit. Use the camera to calculate the speed in m/s or degrees per second of the pole rolling in without the activation strap, and then do the same thing with the activation strap. Compare the two numbers to see if the strap actually slowed the poles rotation at all.
****As far as the design:
In the video you kind of just quickly use a pole to flick the activator, but you do so by a way that has nothing to do with vaulting (i know it just shows how it works). But that activator foam piece that is moving is about 6 inches tall and appears to stop at vertical because of the foam you have behind it or because of how the mat would be. So now there is a piece of foam that may or may not be able to fall far back enough to match the taper of the box. Also because it is narrower than the back of the box, if the vaulters plant is a little crooked and for some reason starts to bend to the right and then when they swing through it switches to the right like it is supposed to, the pole will catch onto the foam activator.
I honestly really liked the idea with the string or the one in the original video where you seemed to have like a noodle or something on the string. I know the new foam activator may make it easier to reset, it just looks like it could cause more problems.

Re: INTRODUCING PV BODY GUARD!!!
Thank you for your in good comments and observation!
Let me try to address your questions and concerns!
You are correct on this note thank you.
Yes it take this amount in lbs to move the new activator you are correct this far down is very little resistance.
Yes that is what I accomplished with the load cell we have on the flex machine.
The newer models will have improvement / upgrades that will speed of set-up and improve release of the activator.
Here are new shoots to help you. Jerry Hock has done a lot of study on this new concept to speed the set up and keep the event moving. I think he has done a great job so far don't you .
